Roger,
I installed the 6200.13 screens on my two 6080s for my 150g and they do a great job of diffusing the flow so that my sandbed isn't blown around anymore. I was also able to use the normal impellors with both Streams vs. using one with the detuned impellor you sent to me with a few millimeters shaved off the blades.
I think the best thing about these screens is that although I think you're pushing the same volume of water as with the normal screens, the water is being pushed around in a wider stream at a lower velocity. This helps decrease the splashing at the surface of the water (my Streams are pointed slightly upwards) and the excess current that was too much for some areas of my tank. Since I never turn off my Streams, I also don't have to worry about anything swimming into the larger output.
